Toxicity and bioavailability of mercury in spiked sediments on Hyalella curvispina Shoemaker, 1942
(Inderscience Enterprises, 2013)
Effects of novobiocin and methotrexate on the benthic amphipod Ampelisca brevicornis exposed to spiked sediments
(Elsevier B.V., 2016-12-01)
The marine amphipod Ampelisca brevicornis was used as model organism of benthic macrofauna to assess the possible adverse effects of pharmaceuticals bound to sediments. Organisms were exposed to sediment spiked with ...
Ensayos de toxicidad de sedimentos con Hyalella pseudoazteca con cobre como tóxico de referencia
(Instituto de Limnología “Dr. R. A. Ringuelet”, 2008)
The suitability of Hyalella pseudoazteca as a test organism for sediment toxicity bioassays and the employment of the sediment from Las Flores stream as a solid control matrix were evaluated. The animals were collected ...

This work aimed evaluates the Alto Jacaré-Guaçu rivers basin quality through physical, chemical and biological and ecotoxicological analysis. Samples of water and sediment were collected in April /07; July/07; October/07 ...
Sublethal effects in Perinereis gualpensis (Polychaeta: Nereididae) exposed to mercury-pyrene sediment mixture observed in a multipolluted estuary
(Springer, 2017-05)
Starch composition of maize grains is of great importance when used in animal feed and many processing industries. Maize production involves hybrids with different kernel composition and hardness, sown at areas that range ...
Multibiomarker responses and bioaccumulation of fipronil in Prochilodus lineatus exposed to spiked sediments: Oxidative stress and antioxidant defenses
(Academic Press Inc Elsevier Science, 2021-08)
Fipronil is a current use pesticide, widely used in many crops, commonly adsorbed to sediments of aquatic environments. The purpose of this study was to evaluate the biomarker responses and fipronil distribution pattern ...
Reversible intermittent flow-injection determination of mercury in sediments and vinasses by cold vapor atomic absorption spectrometry
(1999-12-01)
A reversible intermittent flow-injection procedure is proposed for the automated determination of mercury in sediments and vinasses by cold vapor atomic absorption spectrometry, CVAAS. Solutions of sample and stannous ...
